Introduction: Although the majority of Growth Hormone insensitivity syndrome (GHIS) cases are classical, the spectrum of clinical phenotypes has expanded to include ‘atypical’ GHIS subjects with milder phenotypes due to very rare heterozygous GHR mutations with dominant negative effects.Case description: A 13 year old pubertal boy was presented with short stature (−1.7SD) and delayed bone age (11 6/12). Final adult height was &#8...

Background: PanEuropean(SIOP) trials of treatment for childhood brain cancers (medulloblastomas/PNET) showed a 5% survival advantage with ‘sandwich’ gonadotoxic chemotherapy (CT) over surgical excision, neuraxial radiation and tumour boost (RT) alone. But this was tempered by a reduced quality of survival at 7 years.Objective: To assess the long term prevalence of subfertility after CT with/without neuraxial radiation.<p class="a...

Background: McCune–Albright syndrome (MAS) is defined by skin, bone and glands disorders, due to activating mutations in the GNAS1. Clinical presentation is heterogeneous. Reports about GH excess in MAS patients are scarce.Case report: We present the case of an 8-year-old male, previously diagnosed with mono-ostotic fibrous dysplasia of the skull, referred due to signs of pubertal development since the age of 6. The patient presented only 1...

Background: PHA1 is a rare inherited disease characterized by resistance to aldosterone action and distinguished in two forms: the autosomal dominant renal form caused by mutations of the NR3C2 gene (MR) and the autosomal recessive systemic form caused by mutations of the subunit genes SCNN1A, SCNN1B, SCNN1G of the epithelial sodium channel (ENaC). The classic phenotype of the autosomal recessive form of PHA1 is usually severe, lifelong, and expressed with mu...

Background: Osteoprotegerin (OPG) is a cytokine of the tumour necrosis factor receptor family, expressed in various cells types of the body including osteoblasts and endothelial cells. It acts as a soluble decoy receptor of RANK ligand preventing stimulation of osteoclastogenesis. In adults, subclinical hypothyroidism (SH) has been associated with cardiovascular complications. Furthermore several studies have linked OPG levels to increased cardiovascular risk.<p class="abs...

Background: Pseudohypoaldosteronism is a rare condition of renal or systemic resistance to aldosterone, divisible into separate clinical presentations, each with a distinct physiological and genetic basis. Transient pseudohypoaldosteronism is a secondary form, characterised by reduced glomerulofiltration rate. It has been described in infants with obstructive uropathy and urinary tract infections.Method: We present five cases, presenting in infancy with ...

Background: Children with congenital heart disease (CHD) are predisposed to growth failure, due to the decreased intake of nutrients and also due to the increased energy requirements. Growth failure represents a frequent cause of increase of both morbidity and mortality in children with CHD.Objective and hypotheses: Assessment of physical development in children with CHD and identification of significant factors that influence z scores.<p class="abst...

Background: Congenital hyperinsulinism (CHI) is the most common cause of neonatal persistent hypoglycaemia. Current treatment lacks efficiency, and so are methods for differential diagnosis of diffuse and focal histological forms. Novel diagnostic and treatment approaches with the use of another hormone – glucagon-like-peptide-1 (GLP-1) – have been developed. GLP-1 is one of the key factors for maintaining euglycaemia. It stimulates insulin secretion...

Background: SET domain-containing 5 (SETD5) is an uncharacterized member of the protein lysine methyltransferase family, a group best known for its ability to methylate their substrate and, by that, regulate gene expression. Heterozygous pathogenic variants in SETD5 are known to cause neurodevelopmental delay. We present two children with pathogenic variants in SETD5 and vertebral fractures with low bone mass. Individual 1 This 15-year old male of Caucasian an...

Background: ICSI is an assisted reproduction technique (ART) mainly used to overcome male infertility. Nowadays, ICSI is employed frequently due to its high success rate, despite it being highly invasive (i.e. epigenetic risk). Recent studies in ART offspring show a higher incidence of cardio-metabolic risk than in naturally-conceived (NC) controls. Thus, in our prior untargeted metabolomic study between ICSI and NC prepubertal girls, we demonstrated insulin resistance in the ...
